Chapter 9 Maintenance
Only trained people who know how the lift works, must be allowed to service the lift.
To service properly the lift, the following has to be carried out:
•
Use only genuine spare parts as well as equipment suitable for the work required;
•
Follow the scheduled maintenance and check periods shown in the manual;
•
Discover the reason for possible failures such as too much noise, overheating, oil blow-
by, etc.
•
Refer to documents supplied by the manufacture or dealer to carry out maintenance.
Before carrying out any maintenance or repair on the lift, disconnect the power
supply, padlock the general switch and keep the key in a safe place to
prevent unauthorized persons from switching on or operating the lift.
9.1
Ordinary Maintenance
The lift has to be properly cleaned at least once a month using self-cleaning clothes.
The use of water or inflammable liquid is strictly forbidden.
Be sure the rod of the hydraulic cylinders is always clean and not damaged since this may result
in leakage from seals and, as a consequence, in possible malfunctions.
